Relation between heart rate variability and spontaneous and induced ventricular arrhythmias in patients with coronary artery disease

Abstract

Impaired very low and low frequency oscillation of heart rate reflects susceptibility to the spontaneous occurrence of ventricular arrhythmias but may not reflect the instantaneous triggers for life-threatening arrhythmias or a specific marker of the arrhythmic substrate for ventricular tachyarrhythmias.
